Document about the ways to write unit tests for Bolt apps

I am looking to write unit tests for my Bolt API, which consists of an app with several handlers for events / messages. The handlers are both decorated using the app.event decorator, and make use of the app object to access things like the db connection that has been put on it. For example:

# in main.py
app = App(
    token=APP_TOKEN,
    signing_secret=SIGNING_SECRET,
    process_before_response=True,
    token_verification_enabled=token_verification_enabled,
)
app.db = db

# in api.py:
from .main import app

@app.command("/slashcommand")
def slash_command(ack, respond):
    ack()
    results = app.db.do_query()
    respond(...)

The thing is, I cannot find any framework pointers, or documentation, on how I would write reasonable unit tests for this. Presumably ones where the kwargs like ack and respond are replaced by test doubles. How do I do this?

Beginne mit der Bolt for Python-Dokumentation unter https://slack.dev/bolt-python/ und überprüfe die in main.py und api.py gezeigte Handler-Struktur, einschließlich app.command, app.event, app.db, ack und respond. Dokumentiere einen sinnvollen Ansatz für Unit-Tests dieser Handler, einschließlich Test-Doubles für die Handler-Argumente und die Abhängigkeiten von app, mit Beispielen, die das erwartete Verhalten deutlich machen.
